6.4.1 Input/Output Circuit Wiring

The CN9 connector is equipped with a 24 V input/output circuit for controlling external devices and control by external signals.
Set the relevant parameters and use them with care for the wiring since some signals are changeover type, which can be
switched over by parameters. Refer to the description of each function in the relevant sections for details on the function
specifications and settings.

Use switches or relays for wiring that satisfy the input/output (voltage, current) conditions.
Interface name
For digital input signal (CN24)
 If a ground of the external 24 V power is same as the ground of the 24 V power in the drive unit, a fault or abnormal opera-
tion could occur.
 The maximum rising / falling edge transmission delay time is 500 μs.
